4 Claims.

This invention relates to furniture construction and more particularly to a combined chair and desk of the type generally used in schools wherein a desk arm is supported on one side of the chair and overlies a portion of the seat member.

The primary object ci this invention is to provide a new and useful brace for the desk arm of the combined chair and desk construction described hereinabove which allows for ready ver tical adjustment of the chair or desk arm.

A further object of this invention is to provide adevice of the character described wherein the construction is such that the brace is free from projections that might damage c1othing.

A further object of this invention is to provide a device of the character described in which the brace supporting the desk arm is provided with a means for effecting a tight and noiseless connection with the extended portion of one of the rear legs of the chair.

Yet another object of this invention is to provide a device of the character described which is relatively simple in design and construction, inexpensive, easy to manipulate to effect the vertical adjustments, and very eiiicient for its intended purpose.

These, together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way or" example only in the accompanying drawings, wherein:

Figure 1 is a perspective view ci the invention shown in position on a chair;

Figure 2 is a side elevational view or" the invention and illustrating different vertical positions;

Figure 3 is fragmentary enlarged side elevational view of the invention illustrating the manner of securing,r the brace to the chair; and

Figure /l is a sectional view taken substantially on the plane of section line 4--4 of Figure 3.

Speciiic reference is now made to the drawings. In the several views in the accompanying drawings and in the following speciiication reference characters indicate corresponding,r elements throughout.

Indicated generally at Ill is a chair having iront legs I2 and rear legs I4 supporting a seat member I the rear legs being extended as at IB to support a backrest 2B. It is preferred that the front and rea-r legs as well as the extensions le be constructed of angles.

l the bolts The present invention is in the form of a vertically adjustable brace and is indicated at 22. The brace is constructed of an elongated bar 24, also preferably of angle construction, which bar includes a forward portion 26 and a downwardly inclined rear portion 28. Integral with or secured to the vertical flange of the forward portion 28 is a horizontal bar 30 which, together with the forward portion 26, serves as a means to secure a conventional desk arm (not shown).

A means is provided for securing in vertically adjusted positions the forward portion 26 to one of the front legs I2. This means can take various forms and the one illustrated in the drawings comprises an angle bar 32 depending from the forward portion 25, this bar partially embracing the upwardly extended portion 34 of one of the front legs I2. The front leg I2 and extended portion 3!! are also of angle construction and are provided with vertically spaced apertures 36 adjacent the top and bottom of the front leg. Angle lugs 38 are provided and appropriate bolts 4! are extended through the leg i2 or the extension 34 thereof, the angle bar 32 and the angle lugs 38. Obviously, by extending 4) through a selected pair of the upper and lower apertures 36, the height of the forward portion 26 of the elongated bar 24 can be easily adjusted upon the chair. The preferred means of effecting this adjustment is further described in the patent to Nuberg 1,721,743 issued July 23, 1929.

A means is provided for retaining the rear inclined portion Z8 of the elongated part 2li in adjusted positions upon the extension I!! of one of the rear legs I4 and this means will be described immediately hereinafter. As stated earlier, one of the rear legs I 4 on the extension I8 is of angie construction and one flange I2 thereof is provided at the extended portion I8 with a plurality of vertically spaced slots 44. The free end of the rear portion 2i! is provided with an angulated bifurcated portion 45, the furcations 46 and 45 of which are adapted to extend through a pair of adjacent slots 44. The drawines illustrate four slots and consequently, it will be understood that three diierent vertically adjusted positions can be obtained as a result. It will be understood, however, that any number of vertically spaced slots may be appropriately provided.

As will be seen clearly from Figure 4 in particular, the construction of the rear portion 28 and the angulated bifurcated portion 45 is .such that the desk brace can be secured in any 3 vertically adjusted position on the extension I8 of the rear leg I4 tightly and noiselessly. This is accomplished by bending the biurcated portion to provide a portion 48, that is, substantially perpendicular to the longitudinal axis of the rear portion 2S of the elongated bar 24, and it is this portion 48 which extends through the slot 44. The portion -48f is jagain bent at right angles to provide 'a portionV 5i] which lies flat 'against and abuts the inner face 52 of the ange 42 soV that when the brace is properly assembled in the slots, there will be no projections whichfmight possibly damage the clothing of a person sitting in the chair. To insure a tight'i-t,andxprevent any substantial relative movement ybetween theV brace and the extended portion I8 of one of 'the rear legs I4, the bifurcated portion 46. iswbent at a slightly outward angle as at 54 to the ,longitudinal axis of the rear portion 28 of the elongated bar 24. This produces an inwardly projecting portion `55 that bears against the outer face v58 vof Yt-he flange '42 and` produces Ya noiseless -t'ightt when the furcations are `fully engaged -i-n `the pair of ladjacent slots 44.

In View yof the foregoingdescription taken in conjunction with the accompanying drawing 'it isbelieved that a clear understand-ing of the device wil-lfbe quite apparent to those skilled in this art. -A more Vdetailed vdescription is accordingly deem'ed unnecessary.

It` `is tobe understood, however, 'that even 'though there isv herein shown and described a preferred embodiment-of the inventionv the same is susceptible ft'o certain changes fully com-preh'ended by the described and they scope Yof the appended claims.

j Having described the invention, what is claimed as new is:

l1. In a chair having front and rear legs, a seat member and a back'member, said rear legs being extended to secure the back member; a Vdesk arm brace comprising an elongated bar having a forward ,portion and a rear 'downwardly inclined portion integraltherewith, said forward portion being adapted to secure a desk arm, means vfor securing said forward portion on one of said front legs in vertically adjusted vpositions and means for securing said rear portion on the ex- 'spirit of the invention as herein tended portion of one of said rear legs in vertically adjusted positions, said last-named means including vertically spaced slots in said extended portion of said one rear leg, and an angulated bifurcated member at the free end of said rear portion having the iurcations positioned in a selected pair of adjacent slots.

2. The combination of claim 1, wherein said one rear leg and extended Vportion are of angle construction, said slots being provided in one `flange of said extended portion, each furcation I of saidbifurcated member being bent to form a portion substantially perpendicular to the longiftudina'l i'axis of said rear portion of said bar and extending 'thrl'lgh `One of said slots and a further portion bent perpendicular to said first bent por- ,tiongsaid Vfurthersjiortion lying flat against and abutting the inner face of said one ange.

3. 'The combination of claim 2, wherein said bifurcated portion is disposed at a slight outward angle tothe longitudinal axis of said rear portion to provide an inwardlyfprojecting portion adapted to `bear against the outer face of said one flange andmaintain a tight engagement of said furcations in saidslots.

4. In combination with a chair having `a iront and a rear-leg, a desk arm brace having a 'forward yend adjustably secured 'to lsaid front leg vrand a downwardly inclined portion adjustably se cured tosaid'rear leg, said rear leg'having aplurality of spaced adjacent slots extend-ing longitudinally thereof, a bifurcated end on said downwardly inclined portion of saidbrace, 'the turcations of saidbifurcated endbeing Vlaterally oiset from and parallel to said brace, said furcations being positioned in a selected pair of adjacent slots.
